TEMPERATURE CONTROL FOR INTERNAL-COMBUSTION Morons.

Application filed March 30, 1925. Serial No. 19,399.

This invention relates to means for heat ing the explosive mixture that is delivered to an internal combustion motor in order that the explosive mixture may be expanded and made more efiective; and it is furthermore an object of the invention to produce a device of the character indicated which will operate prior to the starting of the internal combustion motor in order that the said device will prove effective in cold weather and expedite the starting of internal combustion motors insuch weather.

It is a further object of this invention to produce means for heating the interior ofan automobile body, by delivering heat through a heating register or the like, in order that the interior of the said automobile may be kept at, a proper temperature for the comfort of the occupants.

It is a still further object of this invention to produce means for heating the interior of an internal combustion motor in order that oil or lubricant in such motor may have higher temperature than itwould ordinarily have, a condition which will insure proper action of the lubricant and preserve the operating parts of the mechanism.

It is a still further object of this invention to produce a combined heater and ventilator in order that the interior of the automobile, or the interior of the motor, may be supplied with air under forced circulation during the heated terms of the year, thereby making it possible with the use of one system to either heat or cool the air in the automobile or in the interior of the motor.

WVith the foregoing and other objects in view, the invention consists in the "details of construction, and in the arrangement and combination of parts to be hereinafter more fully set forth and claimed.

In describing the invention in detail, refer-.

ence will be had to the accompanying draw' in'gs forming part of this applicationwherein like characters denote corresponding parts in the several views, and in which- Figure 1 illustrates a View in elevation showing a device embodying the invention applied to the motor and interior of an automobile body;

Figure 2 illustrates an enlarged detail view showing the device applied to an intake manifold;

Figure 3 illustrates a view in elevation,

partly in section, of the device shown in Fig. 2, on an enlarged scale;

'Figure 4 illustrates a view in elevation of an exhaust manifold and pipes as a modified auxiliary heater;

Figure 5 illustrates a sectional view of the casing showing an auxiliary fuel burner for heating the interior of the casing; and- .Figurefi illustrates a similar view of the casing having a modified auxiliary heating device. I

' In these drawings, 5 denotes an internal combustion motor having an intake manifold 6 connected to a suitable carburetor 7, which parts may be of. any appropriate type. and are not described in detail.

A casing 8, in this embodiment of the invention forms a heating chamber in which an electric heater 9 may be located, and

the said heater may be supplied with current from a suitablebattery 10 and from a gen.- erator, (not shown), such as is employedyin association .Wlth automobile motors of conventional types. The casing is'incommunicommunication betweenithe casing and the intake manifold so that a greater or less amount ofheated air may be supplied to the intake manifold for'the purposes heretofore-stated. The casing also communicates with branch pipes 14 and 15, the former of which has a conduit or pipe 16 connected to it leading to a register 18 and supplied with a Valve 19 of any appropriate type, similar to the Valve 13.- The pipe 16 also has a coupling 20 to which a conduit or pipe 21 is i connected and the said pipe 21 may lead to the interior of an automobile through a register 22, and the said pipe 21 may be provided with a valve 23 whereby passage through thepipe may be regulated.

The pipe .15 has a conduit or extension 24: leading to the interior of the'crank case 25 for the purpose of supplying air to the crank case in a heated state for raising the temperature of the interior of the motor in winter, and under pressure to effect itscirculation through the interior of the motor for cooling the interior of the motor in suinmerthebreather pipe 25. can be relied upon ver of. the first class 27. The lever 27 is pivoted at 28 between forks 29 provided at the extreme outer end of the main lever 7. The block 15 is provided with an extension- 30 carrying. a pin 31 engaging a slot 1n the lower arm of the lever 27.

As best shown in Figure 3, the lever 27 is ponent of movement which gives the desired zero correction for" the scale.

As best shown in Figures 2 and 3,. the spring 2 extends upwardly between the portions 14 of the main lever. The dash pot 33 of the scale is also located between these extensions. The piston rod 34 of the dashpot is. connected to a yoke 35 which is pivoted to the extensions 14 at 36. The yokes 35 and 20 are connected at their upper ends by a link 37 This construction is found in operation to provide a freely working dashpot at all times. The piston rod 345 does not extend through a tight packing, but extends through anopening 88 in the top of the dash-pot, which opening is materially larger than the piston rod 34,
